Technicians from Greenlight Network were working Tuesday to restore internet service to customers in Rochester's Upper Monroe and Swillburg neighborhoods.

Fallen power lines are to blame for the outage, which began around 11:30 a.m. Monday.

Casey Henninger, a company spokeswoman, said the outage was caused by downed power lines belonging to Rochester Gas and Electric Corp. that damaged a fiber optic line.

Greenlight crews had been on standby while RG&E worked to repair the power lines.

That work was completed late Tuesday afternoon, according to Henninger.

"RG&E has cleared the live wires and have given us the 'greenlight' to begin our repair work," Henninger said just after 4 p.m. "Our field technicians are currently on site working to restore services to all impacted customers. We estimate service being restored for customers in the next four hours."

Henninger said that all impacted customers had been notified and the company would provide additional updates via Greenlightnetworks.com and on Twitter @GLNSupport.
